'IO ALL WHQM IT MAY GONOERN:

Be it known that I, EDWARD M. JUDD, of Wolcottville, in the county of Litcheld, and State of Connecticut, have invented, made, and applied to use a certain new and useful improvement: in Shade Rack Pulleys; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specication, wherein- Figure I is a vertical section of said pulley and rack; and

Figure 2 is a rear elevation of the same.

Similar marks of reference denote the same parts. V

' Cord pulleys for curtain fixtures have heretofore been made with a case in which the pulley stockslides, and is held by friction produced by a Wedge also fitted to slide in the same stock. This is liable to become jammedand so tightly set that diiculty is experienced in slaclening the cord. Other cord pulleys have been made with a rack, and either a spring 'pawl or a lever pa'\vl,"acted upon bythe tension of the cord. Both these forms are objectionable on account of the ditliculty experienced in slackening the cord when under strain.

The nature of rny said invention consists in a stock carrying the sh'eave o1' pulley, andrk having a tooth, taking the teeth of a rack, on the back ofthe slide, in combination with a slidingelamp that'retains the teeth togethcijand said clamp not acting. by friction is always in a condition to be moved with facility, and the teeth, being held together, take all strain, so that thc cord of the curtain inture is retained xrith the proper tension. I

In the dra'nmg,`a is the -slide attached at its ends ns usual by nails Vor screws; I; I) are the teeth on the back edges of the longitudinal slot, in which is entered, from one end, the stock c, carrying the shcavelcr pulley f; iis the tooth across one end of the stock c, taking the teeth I). g is the clamp, fitted also to slide in a, and having an arm, L, that passes down behind thc tooth z', to keep it in Contact with the teeth Z1, when thc parts have beenfproperly placed to produce the rcquireddtension on the cord. I

What I claim, and desire to secure by Letters Patent, is-

' The stock c of the pullcyf, having a tooth, t', taking the teeth on the inside of the slide a, in combination with the sliding clamp g for holding said tooth to its place, as set forth.
